Referring to Figures 1 and 2, the server rack 100 according to an embodiment of the present invention may include a main body frame 10 and a tag member 20.

Hereinafter, a server rack 100 according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

The server rack 100 includes an opening on the front and may include a receiving space inside which the electronic device 1 is mounted. Various types of electronic devices 1, such as server devices, can be mounted within the main body frame 10, and a plurality of electronic devices 1 can be mounted in the accommodation space in the height direction of the server rack 100.

Here, the user can detach each electronic device (1) from the server rack (100) for management of the electronic device (1) mounted in the server rack (100), and then place it back into the server rack (100). It can be installed. At this time, the user can directly attach or detach the electronic device 1 from the server rack 100, but depending on the embodiment, it is also possible to use a robot (not shown) for the user's convenience. In other words, a dedicated robot can be used to perform the function of detaching the electronic device 1 from the server rack 100, delivering it to the user, and then mounting it back on the server rack 100.

In this case, the robot needs to determine the exact location of each electronic device 1 mounted in the server rack 100 and accurately control the manipulator for mounting or detaching the electronic device 1. To this end, visual servoing can be applied to the robot, and a plurality of tag members 20 can be included on the main body frame 10 of the server rack 100 to support visual servoing. there is.

Specifically, the main body frame 10 may include an upper plate 11, a lower plate 12, a vertical frame 13, and a holder 14.

As shown in FIG. 1, the upper plate 11 and the lower plate 12 may be provided in a rectangular shape, and depending on the embodiment, they may be implemented in various polygonal, circular, or oval shapes other than rectangles.

A plurality of vertical frames 13 are provided to connect the upper plate 11 and the lower plate 12 in the height direction. Depending on the embodiment, as shown in Figure 1, it may include four vertical frames (13a, 13b, 13c, 13d) connecting the corners of the upper plate 11 and the lower plate 12. The number of vertical frames 13 included in the main body frame 10 can be varied depending on the embodiment.

The tag member 20 can be coupled to the vertical frames 13a and 13c located on the front of the main body frame 10, and the left side vertical frames 13a and 13b located on the left side of the main body frame 10, A first mounting portion 14a and a second mounting portion 14b may be connected to the right vertical frames 13c and 13d located on the right side, respectively.

The holder 14 may include a first holder 14a and a second holder 14b, and the first holder 14a and the second holder 14b are each located inside the main body frame 10. It is guided in this direction and can support the electronic device 1 mounted on the top. Here, although one stand 14 is shown in Figure 1, a plurality of stands 14 can be connected to the vertical frame 13 in the height direction, and each stand 14 can individually support an electronic device. You can.

Referring to Figure 3, the electronic device 1 may be mounted in the server rack 100 in such a way that a portion of the lower surface is supported by the first holder 14a and the second holder 14b. That is, since the middle part of the lower surface of the electronic device 1 is not supported by the holder 14, the electronic device 1 is placed in the server rack 100 by lifting the middle part of the lower surface of the electronic device 1. ) can be taken out or put in.

Meanwhile, the electronic device 1 mounted on the server rack 100 can be mounted or detached by a robot (not shown), and the robot selects the input device from among the plurality of electronic devices 1 mounted on the server rack 100. You can specify the received electronic device, detach it, and then move it. Here, due to the structure of the holder 10, the robot can easily attach and detach the electronic device 1 by simply lifting it using a manipulator.

The tag member 20 may be coupled to the front of the main body frame 10. Here, the tag member 20 may include a tag image T that provides location information of a plurality of unit spaces dividing the accommodation space. That is, the accommodation space of the server rack 100 may be pre-divided into a plurality of unit spaces, and the tag images T may be attached to positions corresponding to each unit space. Here, the unit space may be determined by international standards or standards for the server rack 100.

The tag image provides a location identifier for each unit space and a visual fiducial corresponding to the unit space, and can be implemented with an AprilTag or aruco marker. However, it is not limited to this, and any type of tag or marker can be used as a tag image as long as it provides a location identifier and a visual reference point.

A camera may be attached to the robot, and the tag image included in the tag member 20 may be recognized using the camera. In this case, the robot can extract the location identifier corresponding to each tag image from the tag image and check whether the extracted location identifier matches the input location identifier. In other words, each location identifier can be set in advance to correspond to each unit space included in the accommodation space, and when instructing the robot to attach or detach the electronic device 1, the location of the electronic device 1 It can be provided by entering the location identifier corresponding to . Accordingly, the robot can recognize each tag image and find a location identifier that matches the input location identifier. For example, a position identifier may be set as a series of numbers for each unit space located from the bottom to the top of the main body frame 10, and depending on the embodiment, a position identifier may be used to distinguish each server rack 100. It is also possible to include additional identifiers.

Afterwards, if the robot finds a tag image containing a location identifier that matches the input location identifier, it can control the position and pose of the manipulator using the tag image. The shape contained within the tag image can provide the robot with a visual reference point, so the robot can calibrate the robot's camera coordinate system based on the tag image. Through this, it is possible to precisely control the position of the manipulator designed to correspond to the camera's coordinate system.

In other words, if the coordinate system recognized by the robot is different from the coordinate system of the server rack 100, accidents such as the robot's manipulator colliding with the electronic device 1 or the electronic device 1 falling during installation or detachment may occur. there is. Therefore, the robot can be calibrated based on the tag image so that it can operate precisely through visual servoing. Here, the correspondence relationship between each location identifier and unit space may be stored in the robot or in a separate control server (not shown) that controls the robot.

Meanwhile, according to an embodiment of the present invention, the tag member 20 can be implemented as shown in FIG. 4. That is, the tag member 20 may include a plurality of tag images T positioned at a set interval in the height direction on one base plate 21. Here, the length of the base plate 21 can be set in advance, and through this, one base plate 21 can include a set number (for example, 5) or more tag images T. Depending on the embodiment, a plurality of tag images T may be directly printed on the base plate 21 using UV (Ultra Violet) printing, etc. In this case, attachment errors that occur in the process of attaching the tag images T on the base plate 21 can be prevented. However, depending on the embodiment, after printing a printed matter including a plurality of tag images T, the printed matter is attached to the base plate 21 using adhesive or double-sided tape, etc., thereby forming the tag member 20. It is also possible to implement . As shown in FIG. 5, the tag members 20 may be respectively coupled to the front of the main body frame 10.

According to another embodiment of the present invention, it is also possible to implement the tag member 20 as shown in FIG. 6. That is, the tag member 20 may include a bracket 22 coupled to the main body frame 10 in the height direction, and a tag image T displayed within the bracket 22. Here, as shown in Figure 6, one tag image may be included in one bracket 22, but depending on the embodiment, a plurality of tag images T may be included in one bracket 22. It is also possible to implement it. However, since the bracket 22 has a short shape, a relatively small number (for example, 1 to 2) of tag images T may be included in the bracket 22. As shown in FIG. 6, the tag member 20 can be implemented by printing the tag image T on a separate printed matter and then attaching the printed matter to the bracket 22. Here, the printed material may be attached to the bracket 22 using adhesive or double-sided tape. However, an embodiment in which printing is performed directly on the bracket 22 through UV printing or the like is also possible.

Figure 7 is a diagram showing a mounting error of a tag member according to an embodiment of the present invention. Mounting error is an error that occurs when coupling the tag member 20 to the main body frame 10, and may occur due to equipment errors such as hole dimensions. In some cases, a rotation error may occur when the tag member 20 rotates, and when a rotation error occurs, the manipulator may be operated in a tilted state, causing problems such as collision with the electronic device 1. may occur.

Referring to Figure 7(a), in the case of the tag member 20 using the bracket 22, since the gap H1 between the fastening holes of the bracket 22 is relatively short, the maximum error in the position of the fastening holes ( When D1) occurs, a relatively large rotation error (θ1) may occur.

However, in the case of the tag member 20 using the base plate 21 as shown in Figure 7(b), the gap H2 between the fastening holes is relatively long, so the maximum error D2 in the position of the fastening holes occurs. Even so, a relatively small rotation error (θ2) may occur. For example, if the distance between the fastening holes of the bracket 22 is 44.5mm (1U) and the distance between the fastening holes of the base plate 21 is 444.5mm (10U), the rotation error θ1 is 0.64 degrees, and the rotation error θ1 is 0.64 degrees. Error θ2 may be as high as 0.064. Therefore, when using the tag member 20 based on the base plate 21, an effect that is robust against rotation error can be obtained.

Additionally, robots can perform various services while moving within target areas such as data centers. Here, the target area can be an indoor space such as a building, and the robot can move within the target area by autonomous driving, but positioning of the robot's position, control of movement, and operation of the manipulator can be performed by the control server. there is. In other words, the robot can perform actions such as movement through communication with the control server. Depending on the embodiment, it is possible to perform overall control by performing part of each control in the robot and control server.

The robot may include a camera, and the camera can be used to capture surrounding images and tag images corresponding to the robot's movement. The robot can transmit surrounding images and tag images to the control server, and the control server can control visual servoing for the robot based on the received surrounding images.

Depending on the embodiment, the robot may further include various sensors, such as an IMU (Inertial Measurement Unit) sensor, a wheel encoder sensor, and a lidar sensor, in addition to the camera.

The control server can communicate with robots located in the target area through a network and can control various operations, including the movement of the robot. Here, the communication method between the control server and the robot is not limited, and not only a communication method utilizing communication networks that the network may include (e.g., mobile communication network, wired Internet, wireless Internet, broadcasting network, satellite network, etc.), but also communication methods between devices. Short-range wireless communication may also be included. For example, networks include personal area network (PAN), local area network (LAN), campus area network (CAN), metropolitan area network (MAN), wide area network (WAN), broadband network (BBN), Internet, etc. It may include one or more arbitrary networks among the networks. Additionally, the network may include, but is not limited to, any one or more of network topologies including a bus network, star network, ring network, mesh network, star-bus network, tree or hierarchical network, etc. .

The control server may be implemented as a computer device or a plurality of computer devices that communicate with the robot through a network to provide commands, codes, files, content, services, etc. Depending on the embodiment, it is also possible to implement the control server in the form of a cloud server.
